摘　　要：战场环境中信息类型错综复杂,目标信息描述已成为战场目标提取的重要环节,而目标信息中的目标轨迹则是决策者重点关注内容。战场目标轨迹点数据量巨大,导致提取目标所有轨迹点速度缓慢。针对该问题,提出了一种采用少量机动点描述轨迹以实现快速提取目标轨迹的算法,即基于机动检测的目标轨迹快速提取算法。该算法在传统交互式多模型(IMM)算法基础上,引入了机动因子并增加了机动检测,获得了目标轨迹机动点,从而形成机动轨迹,达到目标轨迹快速提取。仿真试验表明,该算法能有效获取目标机动轨迹的机动拐点,实现了目标轨迹的快速提取。The information type in the battlefield environment is complex.The target information description becomes an important part of the battlefield target extraction.In the target information,and the target trajectory of the target information is the focus content of the decision maker.A number of the battlefield target trajectory points reduce the target extraction speed.Aimed at the problem,a rapid extraction target trajectory algorithm is proposed by using a small number of maneuvering points to describe the trajectory,that is,the target trajectory rapid extraction algorithm based on maneuver detection.The algorithm is based on the traditional interactive multimodel（IMM）algorithm,the maneuver factor and the maneuver detection are introduced,the target trajectory points are obtained,thus the maneuver trajectory is formed,realizing the rapid extraction target trajectory.The simulation experimental results show that the algorithm can effectively obtain the maneuver inflection points of the target maneuver trajectory and realize the rapid extraction of the target trajectory.
